Oh that was why I was confused, I thought the light throwing concept was determined by how long I held the mouse down and where I placed it. Again awesome concept, I did notice the UI but that's stuff that can be worked on I'll have to download the game to check it out more once the jam is done.
lol no I have not submitted mine yet, most likely last minute or Friday hoping to get most of it done by tomorrow so I can figure out how to compile it for being able to be played on the computer and Android. I'm using libGDX and native code so it's been a lot of work getting most of the code for my idea to work with the only 2 color aspect.
I did find out how to play your game by maximizing the screen, which also shows the how to the one level when the floors fall threw me off for sure. I couldn't get past it tried 3 times then decided to code some more, next you need to add monsters unless there are some later in the level that would make it epic!
